PDF417 does not encode RS or GS in barcode


I am using some of your products to generate PDF417-- your Barcode Image Generator to generate images and PDF417 Barcode fonts to generate barcodes directly in Crystal Reports . When using either of these products and I attempt to encode the RS (Record Separator) using ~030 or in Crystal Chr(30), and scan them into your ASCII String Decoder (I have ASCII Mode On), I do not see the separators revealed.

When encoding non-printable ASCII functions such as RS, GS and EOT, IDAutomation recommends testing the result with the Barcode Decoder App because it reveals these characters in the result to verify proper encoding.

It is possible to encode RS, GS, and other values into PDF417. The Encoding Mode must be set to Binary. In the Image Generator, set Apply Tilde to checked and set Encoding Mode to Binary.

For Crystal Reports encoder, set Encoding Mode parameter to 0 as in:

(DataToEncode As String, EcLevel As Integer, TotalColumns As Integer, TotalRows As Integer, Truncated As Integer, PDFMode As Integer, ApplyTilde As Integer)

For all other products, to encode these values for PDF417, set the Encoding Mode to Binary and Apply Tilde to True or Checked.

(DataToEncode,0 ,0 ,0 ,0 ,0 ,0 )
